214 ROSACEAE (ROSE FAMILY) 
The top-shaped burs about a quarter-inch long, the ring of hooked 
bristles ascending nearly in a single row. 
Means of control 
If deprived of leaf growth by frequent cutting throughout the 
growing season, the tubers shrivel and die; in any case no fruits 
should be allowed to mature in the neighborhood of grazing flocks. 
SMALL-FLOWERED AGRIMONY 
Agriménia parvifiéra, Ait. 
Native. Perennial. Propagates by seeds. 
Time of bloom: July to October. 
Seed-time: August to November. 
Range: Connecticut to Ontario, Michigan, and Kansas, southward 
to Georgia and Louisiana. 
Habitat: Sandy alluvial soil ; damp meadows, thickets along streams. 
Stem two to six feet in height with slender branches near the 
top, densely set with bristly, brownish hairs, very leafy, growing 
from fibrous clustered roots. Leaflets nine to nineteen, elliptic to 
narrow lance-shaped, pointed at both ends, sharply toothed, thin, 
finely hairy, with many interposed pairs of small leaflets of varying 
sizes; stipules usually broader than their length, clasping, sharply’ 
toothed. Racemes many-flowered, one to two feet long, the blos- 
soms hardly more than a quarter-inch broad, the petals light yellow. 
Burs small, dilated top-shaped, deflexed on their pedicels, the rows 
of hooked bristles erect, spreading, and reflexed. 
Means of control 
If areas are not too large to make the task impracticable, hand- 
pulling the plants before seed development is well worth while. 
Repeated and close cutting throughout the growing season, depriv- 
ing the roots of all leaf-growth, will finally suppress the weed.
